To otZZ whom it may concern:

Be it known that I, ADRIEN BAUDIN, engineer, a citizen of the FrenchRepublic, residing at Paris, in the Department of the Seine, France,have invented certain new and useful Improvements in Generators ofFluid- Pressure; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to an apparatus for generating fluid-pressure,and especially an elastic fluid consisting of a mixture of hot air andsteam.

The invention comprises means for pumping air through a moistening andcooling chamber and forcing it into a heating-chamber, where themoisture in the air is turned into steam. The mingled steam and hot airare led to any suitable motor.

In the accompanying drawings, Figure 1 is a diagrammatic sectionalelevation of my improved generator. Fig. 2 is a detail view, on anenlarged scale, showing the automaticallyclosing inlet-valve. I

The cooling-chamber b may contain cold water or ice. At the bottom is aninlet-pipe t, provided with an automatically-closing valve, preferablyconsisting of two flat flexible parts set against each other. The upperpart of this chamber communicates with a compartment 5, with which apump-cylinder Z is connected at each end by valves 6 7, which open intosaid cylinder. The pump has a central piston l, which is preferablyconnected with a double bellows or accordion arrangement, whose openends are attached to the walls of the pump-cylinder adjacent to thevalves 6 7. Delivery-valves 8 10 are lo cated opposite the valves 6 7and communicate with a compartment 9, from which a single port leads toa tank (1, opening into it be tween two floating pistons m n. By meansof a pipe '0 compressed air is admitted to the ends of the tank, tendingto force the floating pistons toward each other and exerting an elasticpressure on the cold damp air delivered to the tank by the pump. Fromthe tank the cold damp air can be admitted through a pipe provided witha stop-cock p and a checkvalve t, similar to the valve on the inlet-pipei, to the heating-chamber cf g h. This is inclosed in a furnace c j 0 s,at the lower end of which is some means for heating, such as the lamp a,to which air is supplied through the the chamber 1) the air is cooledand absorbs a large quantity of moisture The pump draws it through thechamber 1) into the compartment 5 and through the valve 6 or 7 at eachstroke of the piston. By the same stroke air is driven out of thepump-cylinder by the valve 10 or 8 into the compartment 9 and thenceinto the tank d against the tension of the compressed air behind thefloating pistons m n. On opening the stop-cock p the cold damp air flowsinto the heating-chamber, where it rapidly absorbs heat and expands, themoisture which it contains being converted into steam. This mixture ofhot air and steam is capable of exerting a pressure which can beutilized to drive a motor, part of the energy being applied to operatingthe pumppiston Z, so that when once started the apparatus operatesautomatically.

I claim- 1. A fluid-pressure generator comprising a chamber containing aquantity of aqueous material, a pump for drawing air through saidmaterial, a chamber into which the cooled and moistened air isdelivered, and means for heating said last-named chamber.

2. A fluid-pressure generator, comprising a chamber containing means forcooling and moistening air, a pump for drawing air through said chamber,a tank for receiving the cold damp air from said pump, and aheaiging-chamber communicating with said tan 3. In a fluidpressuregenerator, a chamber containing cold aqueous material, an inlet-pipehaving a check-valve and opening near the bottom of said chamber, anairpump taking air from said chamber, a pressure-tank receiving air fromsaid pump, and a heating-chamber connected with said tank.

4. A fluid-pressure generator, comprising a chamber containing coldwater, an inletpipe for said chamber having an inwardlyopeningcheck-valve, a compartment communicating with said chamber, an air-pumpconnected with said. compartment, a tank re- ITO ceiving the cold dampair drawn by said pump from the chamber, means for keeping the air insaid tank under pressure, a heatingchamber, a pipe connecting saidchamber with the tank, and a stop-cock in said pipe.

5. A fluid-pressure generator, comprising a chamber for cold water, anair-pump connected with said chamber and drawing air through the water,a tank into which said pump delivers the cold damp air, floating pistonsin the ends of said tank, means for maintaining fluid-pressure behindsaid pistons, a furnace, a heating-chamber in said furnace, and a pipeconnecting said heating-chamber with the tank and provided with astop-cock I 5 'and a check-valve.

In testimony whereof I affix my signature in presence of two witnesses.
